2018-02-22support unit tests with return values that implement `Terminaton`Niko Matsakis-42/+129
Extend `Termination` trait with a method to determine what happens with a unit test. This commit incorporates work by Bastian Köcher <git@kchr.de>.

2018-02-20make `#[unwind]` attribute specify expectations more clearlyNiko Matsakis-1/+73
You can now choose between the following: - `#[unwind(allowed)]` - `#[unwind(aborts)]` Per rust-lang/rust#48251, the default is `#[unwind(allowed)]`, though I think we should change this eventually.

2018-02-14Rollup merge of #48167 - Mark-Simulacrum:remove-allocation-codemap, r=estebankkennytm-3/+5
Remove allocation from width of character function. Locally this seems to eliminate the problem or at least resolve most of the issue. Fixes #48153. r? @estebank
2018-02-14Rollup merge of #48154 - estebank:issue-31481, r=nikomatsakiskennytm-5/+16
Continue parsing function after finding `...` arg When encountering a variadic argument in a function definition that doesn't accept it, if immediately after there's a closing paren, continue parsing as normal. Otherwise keep current behavior of emitting error and stopping. Fix #31481.
2018-02-14Rollup merge of #48130 - ollie27:stab, r=Mark-Simulacrumkennytm-1/+1
Correct a few stability attributes * `core_float_bits`, `duration_core`, `path_component_asref`, and `repr_align` were stabalized in 1.25.0 not 1.24.0. * Impls for `NonNull` involving unstable things should remain unstable. * `Duration` should remain stable since 1.3.0 so it appears correctly in the `std` docs. * `cursor_mut_vec` is an impl on only stable things so should be marked stable.

2018-02-08Add `rustc_args_required_const` to the feature whitelistAlex Crichton-0/+5
Unfortunately left out it means that when the `#![feature(proc_macro)]` flag is in effect it fails to find `rustc_args_required_const` for expansion. This version, however, is verified to work with stdsimd's requirements!
2018-02-07libsyntax/ext: trailing commas in builtin macrosMichael Lamparski-2/+4
Most notably this changes 'syntax::ext::base::get_single_str_from_tts' to accept a trailing comma, and revises the documentation so that this aspect is not surprising. I made this change under the understanding that this crate is private rustc implementation detail (I hope this is correct!). After reviewing all call sites, I believe the revised semantics are closer to the intended spirit of the function.
2018-02-07Rollup merge of #47613 - estebank:rustc_on_unimplemented, r=nikomatsakisManish Goregaokar-17/+14
Add filtering options to `rustc_on_unimplemented` - Add filtering options to `rustc_on_unimplemented` for local traits, filtering on `Self` and type arguments. - Add a way to provide custom notes. - Tweak binops text. - Add filter to detect wether `Self` is local or belongs to another crate. - Add filter to `Iterator` diagnostic for `&str`. Partly addresses #44755 with a different syntax, as a first approach. Fixes #46216, fixes #37522, CC #34297, #46806.

2018-02-02Rollup merge of #47914 - etaoins:improve-char-escape-in-lexer-msg, ↵kennytm-12/+19
r=petrochenkov Improve char escaping in lexer messages Currently ', " and \ are escaped as \', \" and \\ respectively. This leads to confusing messages such as `error: unknown start of token: \\` when encountering a single backslash. Fix by emitting printable ASCII characters directly. This will still escape \r, \n, \t and Unicode characters. Fixes #47902

2018-02-01Auto merge of #47540 - Manishearth:suggestion, r=nrcbors-10/+36
Add approximate suggestions for rustfix This adds `span_approximate_suggestion()` that lets you emit a suggestion marked as "non-machine applicable" in the JSON output. UI users see no difference. This is for when rustc and clippy wish to emit suggestions which will make sense to the reader (e.g. they may have placeholders like `<type>`) but are not source-applicable, so that rustfix/etc can ignore these. fixes #39254
